treat with prednisone in tandem to another med…. what is the diagnosis? what is the other med?

A

sorry i know this was rude but it would have given it away

Dx: Herpes Zoster Oticus
Tx: prednisone + famciclovir or valcyclovir

note: if you said AOE or auditory eustachian tube dysfunction you are technically not wrong cuz these are treated with steroids!
